JOURNAL-BEARING.

Specification of Letters Patent.

Patented March 6, 1906.

To a/IZ whom it may concern.-

Be it known that I, SPENCER NEEMES, a citizen of the United States,residing at Troy, county of Rensselaer, and State of New York, haveinvented certain new and useful Improvements in Journal-Bearings, ofwhich the following is a specification.

The invention relates to such improvements; and it consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

While my improved j ournal-bearing is applicable to journals andtrunnions of all kinds, it is especially adapted for use in connectionwith grate-bars supported by trunnions in side frames of the grate andadapted to be rockedas, for example, in the rocking grate shown in myapplication filed August 19,

1903, Serial No. 169,968.

The objects of this invention are to provide convenient means forinserting the journals or trunnions in the bearings and to prevent thedisplacement of the bearings while the grate-bars are being rocked forthe purpose of shaking or dumping the grate.

Figure 1 of the drawings is a top plan view of a furnace-grate providedwith my improved journal-bearings. Fig. 2 is a side elevation of thegrate-frame. Fig. 3 is a fragmentary view of a portion of the part shownin Fig. 2 made on an enlarged scale.

Fig. 4 is a top plan view of the part shown in' Fig. 3. Fig. 5 1s a viewin perspective of the key detached. Fig. 6 is a similar view of the capdetached. Fig. 7 is a view similar to that shown in Fig. 3 embodying myinvention in modified form.

The grate-bars 1 are supported by trunnions 2 in the bearings located inthe side frames 3 and 4 of the grate. As shown in the drawings, the sideframes 3 and 4 form the pillows for all the bearings and each bearing isprovided with a separate detachable cap 6 and detachable key 7. Thepillows are provided with uprights 8, forming between them seats whichhave oppositely-disposed side walls upwardly and convergently inclinedtoward the contracted open end of the seat, as shown, adapted to looselyreceive I between them a cap 6, which cap is similarly inclined, so thatits sides incline upwardly and inwardly toward each other. For certainpurposes of the invention said seat may be provided with a contractedopen end in any known manner. The caps are made narrow enough so thatthey may be easily inserted in the spaces between the uprights, andafter being inserted a block or key 7 is inserted in the space betweenone side of acap and one of the uprights which forms a slideway toreceive the same, as shown in the drawings, thereby securely locking thecap in position between the uprights.

To prevent the displacement of the de tachable parts lengthwise of thebearings that is, laterally of the grate-frames 3 and 4the inclinedbearing-surfaces of the uprights are provided with a V-shaped groove 10and the sides of the cap are made wedgeshaped to fit said wedge-shapedgrooves, as shown in Fig. 4, and the key is made wedgeshaped on one sideand V-shaped on the opposite side, so as to fit the spaces between oneof the uprights and one side of the cap. It is obvious that thisinterlocking feature may be varied as desired, it only being necessarythat some projection on one part and depression on another should bebrought into engagement with each other, so as to prevent thevdisplacement of the cap longitudinally of the bearing, the verticaldisplacement being prevented by the key 7, as before described.

The inner surface of one of the uprights may be vertical, as shown at 14in Fig. 7, the adjoining side 15 of the cap being also made vertical,the other side of the cap and the other upright being inclined, as shownat 16 and in the other figures of the drawings.

In Fig. 1 at the right-hand end of the figure I have shown the caps andkeys detached, showing the trunnions of the first rocking bar resting inthe bearing of the pillows.

I am thus able to produce a j ournal-bearing especially adapted forgrate-trunnions and the like, which can be cheaply made of roughcastings and which are easily and quickly put together without bolts orscrews and which can be loosely fitted, so as to allow for contractionand expansion and which cannot be displaced or disarran 'ed in use and.which can be easily and cheaply replaced if broken.

The removable block, shown in the form of a cap 6, may be any known formof bearing block adapted to afford more or less bearingsupport to thejournal.

In the preferred form of my invention the journal-bearing is wholly openupwardly when the cap is detached, permitting both side frames 3 and 4to be fixed in their proper position before the grate-bars 1 are placed,thus greatly facilitating the operation of setting up and repairing thegrate. Such an opening between the inclined uprights permits of akey-slideway between the cap and one of such uprights opening at the topthrough the contracted open end of the seat, where it is easilyaccessible. By having the key-slideway open and uprightthat is, openupwardlyand provided with interlocking connections between it and thekey, as shown, the key will not be displaced while the grate is in use,being. held in place by I gravity and the interlocking connections.

What I claim as new, and desire to secure by Letters Patent, is

1. A ournal-bearing comprising in combination a supporting-frameprovided with a seat having a contracted open end; a j ournalbearingblock loosely insertible in said seat; and a key insertible through thecontracted open end of said seat and with said block substantiallyfilling the seat.

2. A ournal-bearing comprising in combination a supporting-frameprovided with a seat having a contracted open end; a journalbearingblock loosely insertible in said seat having one of its sides engageablewith the side wall of said seat, and its opposite side parallel with theopposite side wall of said seat and forming therewith a key-slidewayopening through the contracted open end of the. seat; and a keyinsertible through the open end of said seat and slideway.

3. A journal-bearing comprising in combi nation a supporting-frameprovided with an open seat having a side wall inclined inwardly towardits open end; and a journal-bearing block and key separately insertible,the key after the bearing-block, in said seat and together substantiallyfilling said seat, one of said insertible parts having a side surfaceengageable, and inclined to correspond with, said inclined side wall.

4. A journal-bearing comprising in combi nation a supporting-frameprovided with a seat having a contracted opened end; a j ournal-bearingblock loosely insertible in said seat, and a key interlockable with thebearing-block and separately insertible through the contracted open endof the seat.

5. A journal-bearing, comprising in combination a sup portingframeprovided with an open seat having a side wall inclined inwardly towardits open end; a journal-bearing block and key separately insertible, thekey after the block, in said seat through the open end thereof, saidblock having an inclined side parallel with said inclined seat-wall, andsaid key having its opposite sides engageable, and corresponding ininclination with, the respective inclined seat-wall and inclined side ofthe j ournal-block.

6. A journal-bearing comprising in combination a supporting-frameprovided with an open seat having its side walls inclined inwardlytoward the open end thereof and each formed with a longitudinal V-shapedgroove; a journal bearing block loosely insertible within said seathaving its opposite sides formed with similarly V-shaped tongues andcorresponding in inclination with the respective seat-walls with one ofwhich one side of said cap is engageable; and a key insertible in saidseat having its opposite sides corresponding in inclination with one ofsaid seat-walls and the neighboring side of said cap between which saidkey is insertible through the open end of the seat and having on oneside a V- shaped tongue fitting the groove in said seatwall andprovided. on the opposite side with a similar V-shaped groove to receivethe tongue on the neighboring side of the block.

7. A journal-bearing comprising in combination a pillow provided with anopen seat leading to a journal-bearing surface having the seat-wallsinclined inwardly toward the open end thereof and each formed with alongitudinal V-shaped groove; a cap insertible within said seat havingon its inner end a complementary journal-bearing surface and having itsopposite sides formed with V-shaped tongues and corresponding ininclination with the respective seat-walls with one of which one side ofsaid cap is engageable 3 and a key insertible in said seat having itsopposite sides corresponding in inclination with one of said seat-wallsand the neighboring side of said cap between which said key is insertedand having on one side a V-shaped tongue fitting the groove in saidseat-wall and provided on the opposite side with a V- shaped groove toreceive the tongue on the neighboring side of the cap.

In testimony whereof I have hereunto set my hand this 22d day of March,1905.
